1. How much tiles are Solar street lights generally

The light source tile digital of Solar street lights directly affects its lighting effect. The size of Solar street lights on the market is mainly related to its height:

1. 5 meters of Solar street lights are equipped with light sources: 9 watts-18 watts.

2. 6 meters of Solar street lights are equipped with light sources: 18 watts-30 watts.

3. 7 meters of Solar street lights are equipped with light sources: 30 watts-42 watts.

4. 8 meters of Solar street lights are equipped with light sources: 42 watts -60 watts.

5, 9 meters of Solar street lights are equipped with light sources: 60 watts-80 watts.

6, 10 meters of Solar street lights are equipped with light sources: 80-100 watts.

Second, the larger the Solar street lamp, the bigger the brighter, the brighter, the

The tiles of light are the energy required for a certain amount of light. In general, the higher the tile, the brighter the light, but the greater the power it uses, but for Solar street lightsThe bigger the big one.

The light and darkness of Solar street lights is not completely determined by Watshu, but is affected by various factors such as power, lumen, and configuration. There are some Solar street lights called hundreds of watts and thousands of watts on the market. Many of them are virtual standards.Some, known as 200 watts, may be a 30 -watt lamp, because of the technology and battery technology limited by the battery board, Solar street lamps can not reach 200 watts or even 300 watts and 500 watts.

Therefore, don't blindly believe that the Solar street lights of high -watt counts. For example, Solar street lights installed in the countryside have chosen more than 30 watts earlier, and now it is basically 40 watts, 50 watts, and 60 watts.

1. What facilities and equipment do hydroponic vegetables need

The cultivation and planting of hydroponic vegetables are usually carried out in the greenhouse.In order to ensure the normal and healthy growth of vegetables, light adjustment facilities, ventilation facilities, and temperature and humidity adjustment facilities must be provided in the greenhouse greenhouse.Anti -insects are also hung in summer to prevent insect pests.

The composition of hydroponic facilities and equipment is composed of nutritional solution grooves, seedling equipment, cultivation pools and cultivation plates, liquid adding systems, drainage systems, circular systems, etc.

1. Nutritional tank

Nutritional solution grooves are used to store nutrients. Generally, bricks and cement are made into water sinks.The specific width of the nutritional groove can be flexibly designed according to the greenhouse terrain.

2. seedling equipment

The seedling equipment is used to sow and seedlings, consisting of seedlings and breeding matrix.The seedlings are mostly made of plastic with flat bottoms without leakage. The plate is 60 cm, 30 cm wide, and 3 cm high.The breeding matrix can choose a sponge block or a degradable rock wool block with a large porosity.

3. Cultivation pool and cultivation board

The cultivation pool is the main site of vegetable growth and the main part of hydroponic facilities.vegetables are planted on the cultivation board and placed in the cultivation pool.The root of the vegetables obtains moisture, nutrients, and oxygen from the nutrient solution in the pool, thereby meeting the physiological needs of normal growth.

The cultivation pool is generally made of cement, and its shape and size are different depending on the types of different vegetables. The cultivation ponds for cultivation of leafy dishes are generally large, up to 100 meters long, up to tens of meters wide, and the specific size will be.Depending on the area of the greenhouse.The cultivation pool of fruit dishes is generally smaller, with a length of 3 meters and a width of 1.5 meters.Both cultivation pools are rectangular, and the pool depth requires 30 cm.In addition, the cultivation pond also has ditch types and pipeline types, but these two cultivation pools are mostly used for small -scale production and viewing purposes.

The cultivation board is also known as the implant plate. It is used to fix the root of vegetables to prevent dust invasion, cover the light of light, and prevent the algae from generating and maintaining the temperature of the nutrient solution in the pool.The cultivation board is generally made of polystyrazene board. According to the types of vegetables and the needs of different growth periods, their specifications and sizes are also different. Generally, they are 80 to 100 cm, 50 to 70 cm wide, and 3 cm thick.The planted pores with a diameter of 3 cm are divided into 288 pores, 99 -hole boards, 72 -hole boards, 24 -hole boards, 18 -hole boards, 6 -hole boards, etc. according to the hole distance.

4. Add liquid, drainage system and nutritional fluid circulation system

The governance of hydroponic facilities is generally pumped into the cultivation pool by the pump.The pool is kept 5 to 8 cm deep water Levels, and the facilities that cultivate the pond adding liquid are composed of iron or plastic -made liquid addresses and plastic -made liquid support.

The nutrient solution was pulled out of the pump from the nutritional groove, and the liquid coefficient and the liquid branch Tube entered the cultivation pond, which was absorbed by the root of the vegetables.The nutrient solution higher than the ductal is flowing back to the nutritional groove through the drainage groove to complete a cycle.

2. Homemade hydroponic vegetable planting equipment

Materials: PVC water pipe diameter 110 series, diameter 75 series, 50 series diameter, 110 rpm 75 supplement core, 75 ride 50 supplement core, 110 corners

Bend, 50 corner bend, PVC glue, a bucket or water tank above 30L, a submersible pump (over 2.5 meters), silicone Tube, throat hoop, throat,, throat,, throat,

Timing plug.

tools: saw, electric diamond, open -hole, tape measure, marking pen

Production process:

1. The place where the hydroponic pipeline is placed must be sufficient, and it is best to facing south.Observe the light situation and place hydroponic pipelines in places suitable for planting.There are many forms of hydroponic equipment, including newspaper shelves and box hydroponic devices. Although the structure is different, the principle is that the root system of plants extends into the water to absorb nutrient solution.The root of the plant in the system.Some special plants, such as: the roots of water spinach and green dill are not high in the oxygen content in the nutrient solution, and can also be cultivated by static water.But in general, the flowing nutrients are better, suitable for most vegetables and plants.

2. You can find a lot of hydroponic equipment on Taobao and choose the appropriate direct order.But if you want a set of hydroponic systems that are suitable for your own, you can only DIY.Measure the size and calculate the length of the PVC pipeline you need to purchase the material.It is recommended to use a PVC Tube with a diameter of 110mm. In addition to planting vegetables with leafy vegetables, it can also be used to plant eggplant vegetables such as Pepper, tomato, okra, and strawberries.Even in the 110 pipes, the developed fruits and fruits of Cucumber and loofah have succeeded.The pipelines with a diameter of 75mm are only suitable for planting leafy vegetables, such as lettuce, cabbage, spinach, coriander, etc.

3. When designing, pay attention to the 110 pipes and finally convert it into a 50 Tube with two times. The planting pipes are connected with a 50 -sized Tube.This is to retain a certain depth nutrient solution in the planting pipe, so that the root system of the plant is always soaked in the nutrient solution.If you use only one time to make the core from 110 to 75 sizes, it will only be less nutrients staying in the pipeline. When the root system of the plant is underdeveloped in the early stage, it may not be a liquid surface.The entire hydroponic pipeline should form a circular system.The submersible pump in the bucket pumps the nutrient solution to the water inlet, and the overflowing port will circulate a circle of nutrients and then flow back to the bucket.When designing, it is necessary to consider factors such as the direction of the water flow, the level of the level, the flow, and the low -level pipelines overflowing.4. Measted the size of the pipeline, and after the material is good, use an electric drill and add a hole to drill the pores of the planting basket on the pipe.The size of the opening device is determined according to the size of the planting basket.The previous spacing of each planting hole is 20cm, which can meet the growth requirements of most vegetables.You can adjust the hole distance to 10cm, so that a lot of space can be saved during the seedling period. After the vegetables grow up, the middle vegetable seedlings will be kept at a reasonable distance.5. Pipes and accessories that are meticulous with the size of the size are bonded with PVC glue. Pay attention to as much glue as much as possible to avoid leakage.After sticking to it, you can test the water 24 hours. Observe whether the water flow is normal, and whether there is water leakage and overflow.If the design is reasonable and the construction is carefully, there should not be too much problems in testing water.

6. After the water test is successful, you can add a timer to the power supply of the submersible pump.Because plants do not need too much oxygen at night, they can be set to work for the diving pump from 7 am to 7 days in the evening. After 7 o'clock in the evening, it can be circulated once a hour and a cycle for 10 minutes.

1. How to make green dill Nutritional soil

1. Garden soil: It has a strong water retention and Fertilizer capacity. It can usually be seen in vegetable gardens, fields or roads, and is slightly acidic.

2. Rotten leaf soil: The texture is very loose, and the water retention Fertilizer is very good. It comes from the surroundings of the tree roots. Generally, it is formed after deciduous deciduous after a long time.

3. Sand and soil: The breathability is very good, and it contains many trace elements. After the absorption of plants is conducive to growth.

4. Square: The breathable drainability is very strong, and it can mix it into the soil.

5. Putting the above -mentioned mixed preparations, you can cultivate the green dill.

2. precautions for the production of green dill Nutritional soil

1. Pay attention to its drainage and breathability of homemade green dill soil. If the breathability is not good or the drainage is slow, it is easy to produce water, and the root system is easy to rot.

2. Green Luo likes acidic or neutral soil. If the use of alkaline soil breeding is not conducive to its growth.

3. Many flower buddies like to use pond mud, and think that it is fertile. This soil is not suitable for green dill growth.Because, it is very close, the breathability is very poor, and it is easy to rot with the pond mud.

Third, what kind of Nutritional soil is used in green dill

1. If you want to cultivate the green dill, it is best to choose nutrient soil to cultivate. This is easy to buy. Generally, do not make it. You can buy it directly. The price is relatively cheap.

2. Generally, when the Nutritional soil is used to cultivate the green dill, some stones or granite can be added to the nutrient soil, which can ensure that the soil's breathability is better.

3. In addition to nutrient soil, you can also choose to use sand soil. Do not use other soils, because the air permeability of sand soil can be used to breed green dill.

4. During the breeding, the soil will appear on the soil. Generally, you choose to loosen the soil regularly. It is better to choose the soil once a month to ensure that the soil is loose.

5. During the breeding, the nutritional content of the soil will be absorbed. Therefore, fertilization is needed. Generally, fertilization is used every 2 months. You can choose Organic fertilizer fertilization.

6. If the Green Luo wants to change the basin, the soil of the best root can be changed together, so that it can avoid the phenomenon that cannot be adapted because of changing the soil.

Fourth, what Nutritional soil is the green dill cuttings

1. Great flower raising soil

flowers and friends usually use universal soil on the market. Xiaobian also bought nutrient soil on Taobao before. This kind of soil may not keep up with nutrition. Although the green dill has not high requirements for the soil, the fertile humus soil can be.It is right to grow flowers with loose pot soil, so it is usually matched with Nutritional soil.

2. Prepare Nutritional soil by yourself

It is generally used by self -matched nutrient soil, pine needles and garden soil, as well as perlite. It can be uniformly mixed with a certain proportion.Rooting and germination.

3. The wonderful use of eggshells

Because eggshells are rich in calcium and phosphorus, they can avoid yellowing leaves, and it is also good for the growth of green dill. Green lobes can be burst into pots. flowers can add some eggshells to Nutritional soil.

4. Cutting method

You can find a strong green dill branch, and then put the branches of the branches horizontally in the soil, and then after a while, the green dill can take root and rush into a large pot.
